2022-11-08dmaengine: stm32-dma: fix potential race between pause and resumeAmelie Delaunay1-8/+6
When disabling dma channel, a TCF flag is set and as TCIE is enabled, an interrupt is raised. On a busy system, the interrupt may have latency and the user can ask for dmaengine_resume while stm32-dma driver has not yet managed the complete pause (backup of registers to restore state in resume). To avoid such a case, instead of waiting the interrupt to backup the registers, do it just after disabling the channel and discard Transfer Complete interrupt in case the channel is paused.

When IDXD is not configurable, that means its WQ, engine, and group configurations cannot be changed. But it can be disabled and its state should be set as disabled regardless it's configurable or not.

2022-11-08dmaengine: idxd: Fix max batch size for Intel IAAXiaochen Shen4-6/+38
>From Intel IAA spec [1], Intel IAA does not support batch processing. Two batch related default values for IAA are incorrect in current code: (1) The max batch size of device is set during device initialization, that indicates batch is supported. It should be always 0 on IAA. (2) The max batch size of work queue is set to WQ_DEFAULT_MAX_BATCH (32) as the default value regardless of Intel DSA or IAA device during work queue setup and cleanup. It should be always 0 on IAA. Fix the issues by setting the max batch size of device and max batch size of work queue to 0 on IAA device, that means batch is not supported.

The first IRQ is required, but IRQs 1 through (nb_phy_chans - 1) are optional, because on some platforms (e.g. PXA168) there is a single IRQ shared between all channels.

2022-10-19dmaengine: idxd: Do not enable user type Work Queue without Shared Virtual ↵Fenghua Yu1-0/+18
Addressing When the idxd_user_drv driver is bound to a Work Queue (WQ) device without IOMMU or with IOMMU Passthrough without Shared Virtual Addressing (SVA), the application gains direct access to physical memory via the device by programming physical address to a submitted descriptor. This allows direct userspace read and write access to arbitrary physical memory. This is inconsistent with the security goals of a good kernel API. Unlike vfio_pci driver, the IDXD char device driver does not provide any ways to pin user pages and translate the address from user VA to IOVA or PA without IOMMU SVA. Therefore the application has no way to instruct the device to perform DMA function. This makes the char device not usable for normal application usage. Since user type WQ without SVA cannot be used for normal application usage and presents the security issue, bind idxd_user_drv driver and enable user type WQ only when SVA is enabled (i.e. user PASID is enabled).

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random Pull more random number generator updates from Jason Donenfeld: "This time with some large scale treewide cleanups. The intent of this pull is to clean up the way callers fetch random integers. The current rules for doing this right are: - If you want a secure or an insecure random u64, use get_random_u64() - If you want a secure or an insecure random u32, use get_random_u32() The old function prandom_u32() has been deprecated for a while now and is just a wrapper around get_random_u32(). Same for get_random_int(). - If you want a secure or an insecure random u16, use get_random_u16() - If you want a secure or an insecure random u8, use get_random_u8() - If you want secure or insecure random bytes, use get_random_bytes(). The old function prandom_bytes() has been deprecated for a while now and has long been a wrapper around get_random_bytes() - If you want a non-uniform random u32, u16, or u8 bounded by a certain open interval maximum, use prandom_u32_max() I say "non-uniform", because it doesn't do any rejection sampling or divisions. Hence, it stays within the prandom_*() namespace, not the get_random_*() namespace. I'm currently investigating a "uniform" function for 6.2. We'll see what comes of that. By applying these rules uniformly, we get several benefits: - By using prandom_u32_max() with an upper-bound that the compiler can prove at compile-time is ≤65536 or ≤256, internally get_random_u16() or get_random_u8() is used, which wastes fewer batched random bytes, and hence has higher throughput. - By using prandom_u32_max() instead of %, when the upper-bound is not a constant, division is still avoided, because prandom_u32_max() uses a faster multiplication-based trick instead. - By using get_random_u16() or get_random_u8() in cases where the return value is intended to indeed be a u16 or a u8, we waste fewer batched random bytes, and hence have higher throughput. This series was originally done by hand while I was on an airplane without Internet. Later, Kees and I worked on retroactively figuring out what could be done with Coccinelle and what had to be done manually, and then we split things up based on that. So while this touches a lot of files, the actual amount of code that's hand fiddled is comfortably small" * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: prandom: remove unused functions treewide: use get_random_bytes() when possible treewide: use get_random_u32() when possible treewide: use get_random_{u8,u16}() when possible, part 2 treewide: use get_random_{u8,u16}() when possible, part 1 treewide: use prandom_u32_max() when possible, part 2 treewide: use prandom_u32_max() when possible, part 1

The clk rate range series needed another week to fully bake. Maxime fixed the bug that broke clk notifiers and prevented this from being included in the first pull request. He also added a unit test on top to make sure it doesn't break so easily again. The majority of the series fixes up how the clk_set_rate_*() APIs work, particularly around when the rate constraints are dropped and how they move around when reparenting clks. Overall it's a much needed improvement to the clk rate range APIs that used to be pretty broken if you looked sideways. Beyond the core changes there are a few driver fixes for a compilation issue or improper data causing clks to fail to register or have the wrong parents.

Commit 8c193f4714df ("pwm: tegra: Optimize period calculation") updated the period calculation in the Tegra PWM driver and now returns an error if the period requested is less than minimum period supported. This is breaking PWM support on various Tegra platforms. For example, on the Tegra210 Jetson Nano platform this is breaking the PWM fan support and probing the PWM fan driver now fails ... pwm-fan pwm-fan: Failed to configure PWM: -22 pwm-fan: probe of pwm-fan failed with error -22 The problem is that the default parent clock for the PWM on Tegra210 is a 32kHz clock and is unable to support the requested PWM period. Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by updating the parent clock for the PWM to be the PLL_P.

2022-10-14clk: mediatek: clk-mux: Add .determine_rate() callbackAngeloGioacchino Del Regno1-0/+10
Since commit 262ca38f4b6e ("clk: Stop forwarding clk_rate_requests to the parent"), the clk_rate_request is .. as the title says, not forwarded anymore to the parent: this produces an issue with the MediaTek clock MUX driver during GPU DVFS on MT8195, but not on MT8192 or others. This is because, differently from others, like MT8192 where all of the clocks in the MFG parents tree are of mtk_mux type, but in the parent tree of MT8195's MFG clock, we have one mtk_mux clock and one (clk framework generic) mux clock, like so: names: mfg_bg3d -> mfg_ck_fast_ref -> top_mfg_core_tmp (or) mfgpll types: mtk_gate -> mux -> mtk_mux (or) mtk_pll To solve this issue and also keep the GPU DVFS clocks code working as expected, wire up a .determine_rate() callback for the mtk_mux ops; for that, the standard clk_mux_determine_rate_flags() was used as it was possible to. This commit was successfully tested on MT6795 Xperia M5, MT8173 Elm, MT8192 Spherion and MT8195 Tomato; no regressions were seen.

2022-10-13rtc: cmos: Fix event handler registration ordering issueRafael J. Wysocki1-10/+19
Because acpi_install_fixed_event_handler() enables the event automatically on success, it is incorrect to call it before the handler routine passed to it is ready to handle events. Unfortunately, the rtc-cmos driver does exactly the incorrect thing by calling cmos_wake_setup(), which passes rtc_handler() to acpi_install_fixed_event_handler(), before cmos_do_probe(), because rtc_handler() uses dev_get_drvdata() to get to the cmos object pointer and the driver data pointer is only populated in cmos_do_probe(). This leads to a NULL pointer dereference in rtc_handler() on boot if the RTC fixed event happens to be active at the init time. To address this issue, change the initialization ordering of the driver so that cmos_wake_setup() is always called after a successful cmos_do_probe() call. While at it, change cmos_pnp_probe() to call cmos_do_probe() after the initial if () statement used for computing the IRQ argument to be passed to cmos_do_probe() which is cleaner than calling it in each branch of that if () (local variable "irq" can be of type int, because it is passed to that function as an argument of type int). Note that commit 6492fed7d8c9 ("rtc: rtc-cmos: Do not check ACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger number of systems, because previously it only affected systems with ACPI_FADT_LOW_POWER_S0 set, but it is present regardless of that commit.

The driver prints out 6 lines on startup, which can easily be redcued to two lines without losing any information. Note, to make the types work better, uint64_t has been replaced with ULL to make the unsigned long long match the format in the print statement.

Since composable cache may be L3 cache if there is a L2 cache, we should use its original name composable cache to prevent confusion. There are some new lines were generated due to adding the compatible "sifive,ccache0" into ID table and indent requirement. The sifive L2 has been renamed to sifive CCACHE, EDAC driver needs to apply the change as well.
